Pulmonary Embolism in a Young African American Male: A Diagnostic Challenge.

ABSTRACT

This case report highlights the diagnostic challenges posed by pulmonary embolism (PE) in a young, otherwise healthy 33-year-old African American male with no apparent risk factors. The patient presented with penile pain, swelling, hematuria, flank pain, and rash, and was admitted for balanoposthitis and acute urinary retention. Despite prophylactic heparin, he suffered two cardiac arrests secondary to PE on the fifth day of hospitalization. Prompt thrombolytic therapy and heparin infusion were initiated, but his course was complicated by anuric acute kidney injury requiring hemodialysis, shock liver, and gastrointestinal bleeding. Imaging revealed a substantial thrombus burden in the pulmonary arteries. Notably, a hypercoagulable workup was negative. The absence of typical risk factors, negative hypercoagulable workup, and occurrence of PE despite prophylaxis underscore the importance of vigilance in recognizing atypical presentations. This case emphasizes the need for a high index of suspicion and comprehensive evaluation to diagnose PE in young patients without clear predisposing factors.
